Technique for timeline compression in a data store
First Claim
1. A method for timeline compression in a storage system, wherein digital content of the storage system is backed up to enable restoration of the digital content to one or more points in a timeline, the method comprising:
- selecting a time interval in the timeline;
identifying one or more sets of backup data recorded for the selected time interval, wherein the identified one or more sets of backup data represent at least a portion of old data overwritten during the selected time interval; and
discarding other backup data recorded for the selected time interval, thereby reducing a granularity level of the timeline in the selected time interval.

Abstract
A technique for timeline compression in a data store is disclosed. In one particular exemplary embodiment, the technique may be realized as a method for timeline compression in a storage system, wherein digital content of the storage system is backed up to enable restoration of the digital content to one or more points in a timeline. The method may comprise selecting a time interval in the timeline. The method may also comprise identifying one or more sets of backup data recorded for the selected time interval, wherein the identified one or more sets of backup data represent at least a portion of old data overwritten during the selected time interval. The method may further comprise discarding other backup data recorded for the selected time interval, thereby reducing a granularity level of the timeline in the selected time interval.

14. A system for timeline compression in a storage system, wherein digital content of the storage system is backed up to enable restoration of the digital content to one or more points in a timeline, the system comprising:
-
means for selecting a time interval in the timeline;
means for identifying one or more sets of backup data recorded for the selected time interval, wherein the identified one or more sets of backup data represent at least a portion of old data overwritten during the selected time interval; and
means for discarding other backup data recorded for the selected time interval, thereby reducing a granularity level of the timeline in the selected time interval.

15. A system for timeline compression in a storage system, wherein digital content of the storage system is backed up to enable restoration of the digital content to one or more points in a timeline, the system comprising:
-
a storage medium for storing instructions; and
at least one processor for;
selecting a time interval in the timeline;
identifying one or more sets of backup data recorded for the selected time interval, wherein the identified one or more sets of backup data represent at least a portion of old data overwritten during the selected time interval; and
discarding other backup data recorded for the selected time interval, thereby reducing a granularity level of the timeline in the selected time interval.
